CHOLESTEROL

Too much cholesterol in the blood causes the arteries to harden and narrow. This slows down and may eventually block blood flow to the heart, causing a heart attack.Participants in the 'Life's Simple 7' list study included 13,253 white and African-American men and women in the ongoing Atherosclerosis Risk in Communities Study, launched in 1987 in four U.S. communities.

They were interviewed and examined at the start of the study to determine which health factors they met or followed. About 20 years later, the researchers reviewed cancer registries and hospital records and determined that 2,880 of the participants ended up with cancer, primarily of the lung, colon or rectum, prostate and breast. The findings were published in the journal Circulation.
